Abstract
A sealing vent for a foaming dispenser associated with a squeeze foaming container is described. The vent has an annular structure, with a central aperture encased by a multi-tiered disc section connected to inner facing of a thickened, axial wall. An upward angled, outer flange is connected on an outer facing of the axial wall, and the outer flange is attached at a lower elevation along the axial wall in comparison to the disc section.
Claims22
An annular vent for selectively admitting air into a squeeze foaming mechanism when the mechanism is activated, the vent comprising:
- an wall having a hollow cylindrical shape aligned along a substantially vertical axis;
- an inner flap comprising first, second, and third contiguous sections attached to an inner facing of the wall with the first contiguous section attached to the wall at an angle and the first and second contiguous sections are joined at an elevation above a terminal top edge of the wall;
- an outer flap attached to an outer facing of the wall;
- and
- a central aperture defined by a terminal edge of the third contiguous section of the inner flap.
An annular vent for selectively admitting air into a squeeze foaming mechanism when the mechanism is activated, the vent comprising:
- an wall having a hollow cylindrical shape aligned along a substantially vertical axis;
- an outer flap attached to an outer facing of the wall;
- an inner flap attached to an inner facing of the wall at a different elevation in comparison to the outer flap, the inner flap having first, second, and third contiguous sections where the first contiguous section is attached to the wall, the second contiguous section is disposed at a downward angle relative to the first and third contiguous sections, and the third contiguous section forms an upwardly angled, frusto-conical shape with a terminal edge defining a central aperture having an axial elevation relative to the wall that falls between that of:
- (i) a junction of the first and second contiguous sections and (ii) a junction of the second and third contiguous sections.
